gridview突出显示当前行

是否有内置方法突出显示GridView中当前选定的行？gridview突出显示当前行

我的gridview中的每一行都有一个按钮（通过buttonField）。当用户按下此按钮，背景颜色的变化...我不喜欢这样写道：

Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand 
    If e.CommandName = "Select" Then 
     Dim index As Integer = Convert.ToInt32(e.CommandArgument) 
     Dim selectedRow As GridViewRow = gvTransferOwner.Rows(index) 
     selectedRow.Style.Add("background-color", "#ffcccc") 
    End If 
End Sub

这凸显了该行，但是一旦用户按下另一行的按钮，它仍然保留了所有的颜色先前按下的行。

是否有办法让每次只有一行（当前选定的行）被突出显示？

感谢

如果您使用全局变量来存储正被选择的行的索引，可以每当选择了新行更改排回原来的颜色。

Dim previousSelected As Integer 'global variable to store the last selected index 
Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand 
    If e.CommandName = "Select" Then 
     Dim index As Integer = Convert.ToInt32(e.CommandArgument) 
     Dim selectedRow As GridViewRow = gvTransferOwner.Rows(previousSelected) 
     selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color 
     selectedRow = gvTransferOwner.Rows(index) 
     selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row 
     previousSelected = index 
    End If 
End Sub

在GridView有一个SelectedIndexChanged事件，以及有GridView.SelectedRow Property，你可以在@jonhopkins的回答结合使用。

我在SelectedIndexChanged事件中这样做，它适用于我。

GridView1.Rows[GridView1.SelectedIndex].BackColor = Color.Yellow;

Dim previousSelected As Integer 'global variable to store the last selected index 
Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand 
    If e.CommandName = "Select" Then 
     previousSelected = ViewState("previousSelected") 
     Dim index As Integer = Convert.ToInt32(e.CommandArgument) 
     Dim selectedRow As GridViewRow = gvTransferOwner.Rows(previousSelected) 
     selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color 
     selectedRow = gvTransferOwner.Rows(index) 
     selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row 
     ViewState("previousSelected") = index 
    End If 
End Sub

昏暗previousSelected作为整数

 If e.CommandName = "Select" Then 
      previousSelected = GetVal(ViewState("previousSelected")) 
      Dim index As Integer = Convert.ToInt32(e.CommandArgument) 
      Dim selectedRow As GridViewRow = grvOptionset.Rows(previousSelected) 
      selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color 
      selectedRow = grvOptionset.Rows(index) 
      selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row 
      ViewState("previousSelected") = index 
     End If
